The Complete Guide to Camping and Caravan Gas Equipment — Fuel, Fittings, and Safe Use

Why Gas Powers Outdoor Life

LPG is the dominant fuel for outdoor cooking and heating because it is portable, stores a large amount of energy in a compact cylinder, lights instantly, provides controllable heat, and requires no mains electricity to operate. A single gas cylinder can power a caravan's cooking, heating, and hot water for days — making it ideal for off-grid touring where no other energy source is available.

For tent campers, a small gas cartridge powers a stove for a weekend of cooking. For caravan and motorhome owners, a pair of gas cylinders in the gas locker provides the fuel for a week or more of self-sufficient touring. Understanding how gas equipment works — and how to use it safely — is fundamental to comfortable and safe outdoor life.

Propane vs Butane — What Is the Difference?

Both propane and butane are LPG — they are derived from the same petroleum refining process and both burn cleanly to produce heat. The practical differences matter for outdoor use.

Propane has a lower boiling point (approximately minus 42°C). This means it vaporises (turns from liquid to gas) even in very cold temperatures. Propane works reliably in freezing winter conditions. It is the preferred choice for year-round and cold-weather camping.

Butane has a higher boiling point (approximately minus 2°C). Below this temperature, liquid butane struggles to vaporise — meaning the gas flow decreases and appliances may not function properly in cold weather. Butane is adequate for summer and three-season camping but unreliable in near-freezing or sub-zero conditions.

Operating pressure. Propane operates at a higher pressure than butane. Appliances designed for one may not work correctly with the other unless the regulator compensates. Most modern caravan regulators are set to a standard output pressure (typically 30 mbar) regardless of the input gas type, but always check the regulator's specification.

For year-round use, propane is the safer choice. For summer-only camping, either works. If in doubt, choose propane — it works in all conditions.

Gas Cylinders — Sizes, Types, and Suppliers

Gas cylinders come in a range of sizes, from small portable bottles to large stationary tanks.

Small cylinders (under 5 kg) are compact and portable — suitable for tent camping, small campervans, and occasional use. They are easy to carry and store but provide limited gas capacity. Frequent replacement is needed on extended trips.

Medium cylinders (5–7 kg) are the most popular size for caravans and motorhomes. A 6 kg propane cylinder provides approximately one to two weeks of moderate cooking and heating use for a couple. Two cylinders (with a changeover system) provide continuous supply.

Large cylinders (11–19 kg) offer the longest duration between changes. They are heavier and require more locker space. Common in static caravans, larger motorhomes, and extended stays.

Cylinder suppliers vary by country. In the UK, Calor Gas is the dominant brand (red for propane, blue for butane). Flogas and Camping Gaz are also widely available. In other countries, different suppliers and different cylinder fittings are standard — an important consideration for touring abroad.

Cylinder exchange. Most systems work on an exchange basis — you return the empty cylinder and receive a full one. This avoids the weight and inconvenience of transporting an empty cylinder long distances. Exchange points are typically found at camping shops, fuel stations, and hardware stores.

Disposable Gas Cartridges

For tent camping and small portable stoves, disposable gas cartridges provide a simple, self-contained fuel source.

Threaded cartridges (EN 417 standard) screw onto compatible stoves. They are compact, widely available, and suitable for one to three days of cooking depending on use. When empty, they are discarded (following local recycling guidelines).

Puncture-type cartridges are pierced by the stove on connection. Once connected, they cannot be removed until empty — limiting flexibility.

Cartridge gas is typically a butane-propane blend optimised for three-season use. Pure propane cartridges are available for winter camping.

For extended trips, cylinders are more economical. Cartridges are convenient but produce more waste and cost more per unit of gas.

Refillable Gas Systems

Refillable gas systems allow you to fill your cylinder at an LPG (Autogas) pump — the same pumps used for LPG-fuelled vehicles. This is particularly valuable for touring abroad, where finding a compatible exchange cylinder can be difficult.

How they work. A specially designed cylinder with a built-in safety valve and an external filler connection is filled at an Autogas pump. The system typically includes a filler mounted externally on the caravan or motorhome body, connected by a hose to the internal cylinder.

Advantages. Widely available refuelling (LPG pumps are found at fuel stations across Europe). No need to find compatible exchange cylinders in foreign countries. Cheaper per litre than cylinder exchange in many cases. Reduced waste — no disposable cylinders.

Disadvantages. Higher upfront cost for the system (refillable cylinder, filler, hose, and installation). Some countries have different LPG pump nozzle types — carry a set of adapters. The cylinder must be installed and maintained correctly.

For European tourers, a refillable system is a worthwhile investment — it eliminates the cylinder-compatibility problem that is one of the most common frustrations of touring across multiple countries.

Regulators — Reducing Pressure Safely

Gas stored in a cylinder is under pressure. Appliances require gas at a much lower, controlled pressure. A regulator sits between the cylinder and the appliance system, reducing the cylinder's high pressure to the standard operating pressure required by the appliances.

Operating pressures. Most modern European caravan and motorhome gas systems operate at 30 mbar — a standard that allows the same regulator and appliance setup to work with either propane or butane (the regulator compensates for the different input pressures).

Regulator types. Clip-on regulators attach directly to the top of smaller cylinders. Bulkhead regulators are permanently mounted on the gas locker wall — the cylinder connects to the regulator via a flexible pigtail hose. Bulkhead mounting is the standard for caravan and motorhome installations.

OPSO (over-pressure shut-off) regulators include a safety mechanism that shuts off the gas supply if the output pressure exceeds a safe level — typically due to a regulator failure. OPSO regulators are now required by European standards for new installations and are a recommended upgrade for older systems.

Regulators are not universal. The regulator must match the gas type (propane or butane), the cylinder connection type, and the required output pressure. Using the wrong regulator can result in incorrect gas pressure to the appliances — affecting performance and safety.

Hoses, Pigtails, and Connections

Gas hoses carry gas from the regulator to the appliance system. They must be rated for LPG use, in good condition, and replaced on schedule.

Pigtails are short flexible hoses that connect the gas cylinder to the bulkhead regulator. They have different fittings at each end — one matching the cylinder valve and one matching the regulator inlet. Pigtails are specific to the gas type and cylinder connection standard.

Hose life. Gas hoses and pigtails should be replaced at least every five years (or sooner if inspection reveals cracking, hardening, or damage). The date of manufacture is stamped on the hose.

Connections must be secure. Hand-tighten clip-on fittings firmly. Spanner-tighten threaded fittings (note: propane fittings typically have a left-hand thread — turn clockwise to loosen, anti-clockwise to tighten). After any connection, test for leaks.

Fittings and Adaptors

The world of gas fittings includes an array of connection types that vary by gas type, cylinder brand, and country.

Common fitting types include: clip-on connectors (for smaller cylinders), POL fittings (a standard screw-on connection for larger propane cylinders), butane-nut fittings (21.8 mm left-hand thread), and W20 threaded connections (on many regulators).

Adaptors convert between fitting types — for example, connecting a propane pigtail to a butane cylinder, or adapting a UK fitting to a European cylinder. A set of European gas adaptors is essential for anyone touring abroad.

Ensure every adaptor is LPG-rated and in good condition. A gas leak at an adaptor joint is a serious safety hazard.

Changeover Systems — Automatic and Manual

A changeover system connects two gas cylinders to a single regulator, allowing continuous gas supply. When one cylinder empties, the system switches to the second — either automatically or manually.

Automatic changeover regulators detect when the primary cylinder is empty and switch to the reserve cylinder without interruption. An indicator shows which cylinder is in use and when the primary is empty. This is the most convenient system — you never run out of gas mid-cook.

Manual changeover requires you to physically turn a valve to switch from the empty cylinder to the full one. Simpler and less expensive but requires you to notice when the gas runs out.

For touring comfort, an automatic changeover regulator is a worthwhile upgrade. It ensures uninterrupted gas supply and gives you time to source a replacement cylinder at your convenience.

Gas Locker Requirements

In caravans and motorhomes, gas cylinders are stored in a dedicated gas locker — a compartment designed to contain cylinders safely.

Ventilation. The gas locker must have a vent or drain at the lowest point, opening to the outside. LPG is heavier than air — if a leak occurs, the gas sinks and must be able to escape downward and out of the vehicle. This vent must never be blocked.

Cylinder securing. Cylinders must be secured in the locker with straps, brackets, or clamps to prevent movement during travel. An unsecured cylinder can damage the gas connection and cause a leak.

No ignition sources. The gas locker must contain no electrical connections, lights, or other potential ignition sources.

Sealed from the living area. The gas locker must be sealed from the vehicle's interior so that any escaping gas cannot enter the cabin.

Gas Safety — The Non-Negotiable Rules

Gas is safe when handled correctly. These rules are non-negotiable.

Turn off the gas at the cylinder before travelling. This is a fundamental safety practice for caravans and motorhomes. A gas leak during travel — with vibration loosening connections and no one monitoring the system — can lead to a gas build-up inside the vehicle.

Never use a naked flame to check for gas leaks. Use soapy water (bubbles indicate a leak) or an electronic gas leak detector.

Ensure adequate ventilation for all gas appliances. Never block fixed ventilation openings. LPG combustion produces carbon dioxide and water vapour; incomplete combustion produces carbon monoxide.

Fit a carbon monoxide detector in the living area of any vehicle with gas appliances. CO is odourless and lethal.

Fit a gas leak detector near floor level close to gas appliances and the gas supply.

Never modify gas equipment unless you are a qualified gas engineer. Incorrect modifications can cause leaks, fires, and explosions.

Inspect hoses and connections regularly. Replace cracked, hardened, or damaged hoses immediately.

Leak Testing and Detection

After any connection change — fitting a new cylinder, replacing a hose, or reconnecting after travel — test for leaks.

Soapy water test. Apply soapy water (or a proprietary leak detection spray) to every joint and connection. Turn the gas on at the cylinder. If bubbles appear at any joint, there is a leak. Tighten the connection and retest. If the leak persists, replace the fitting or seek professional help.

Electronic gas leak detectors sound an alarm when they detect gas. They are a permanent safety feature rather than a testing tool — they provide ongoing monitoring for leaks that develop during use.

Annual Gas Safety Checks

A qualified gas engineer should inspect the entire gas system annually. This inspection includes:

Gas tightness test — checking every joint, connection, and appliance for leaks under pressure.

Let-by test — checking that the regulator's shut-off valve closes completely when downstream appliances are off.

Regulator output pressure test — verifying that the regulator delivers the correct operating pressure.

Appliance function check — testing that each gas appliance (cooker, heater, water heater, fridge) operates correctly, with proper flame colour (blue, not yellow), correct combustion, and functioning flame failure devices.

Flue and ventilation check — ensuring that combustion products are properly vented and that ventilation openings are clear.

An annual gas safety check is a condition of many caravan and motorhome insurance policies and is essential for the safety of everyone on board.

Using Gas Abroad — European Touring

Gas cylinder types, fittings, and suppliers vary across Europe. This is one of the most common logistical challenges for touring caravanners and motorhome owners.

The problem. A UK Calor Gas cylinder cannot be exchanged in France. A French cylinder will not fit a UK regulator without an adaptor. Different countries use different cylinder sizes, different valve types, and different connection standards.

Solutions. A refillable gas system (filled at Autogas pumps, which are widely available across Europe). A set of European gas adaptors (allowing you to connect your regulator to local cylinder types). Purchasing a local cylinder and appropriate regulator at your destination (more complex but possible).

Carry adaptors for every country on your route. The most common types cover UK, French, German, Italian, Spanish, Scandinavian, and Eastern European connections. Universal adaptor sets are available.

The Honest Limitations

Gas is finite. Every cylinder empties eventually. Monitor usage and carry a spare or use a changeover system.

Cold weather limits butane. In near-freezing conditions, butane does not vaporise reliably. Use propane for winter camping.

Fittings are not universal. Different countries, different brands, and different gas types use different fittings. Adaptors solve most compatibility issues, but the variety can be bewildering.

Gas equipment requires maintenance. Hoses, regulators, and connections degrade over time. Regular inspection and scheduled replacement are essential.

Gas work should be done by qualified professionals. Incorrect gas installations cause fires, explosions, and carbon monoxide poisoning. This is not an area for DIY experimentation.

Choosing the Right Gas Setup for You

Common Mistakes People Make

Using butane in cold weather. Below approximately 2°C, butane struggles to vaporise. Appliances underperform or stop working entirely.

Not turning off gas before travelling. A gas leak during travel is undetectable until it is too late.

Not replacing hoses on schedule. Hoses degrade over five years. A cracked hose leaks invisibly.

Using the wrong regulator. A regulator matched to the wrong gas type or cylinder delivers incorrect pressure — affecting appliance performance and safety.

Not testing for leaks after connecting a new cylinder. A loose connection leaks gas. A soapy water test takes seconds and prevents serious consequences.

Not fitting a CO detector. Carbon monoxide from incomplete combustion is a silent killer.

Touring Europe without adaptors. Being unable to connect to a local gas cylinder in a foreign country is frustrating and avoidable.
